HOT-AIR REGISTER.

SPECIFICATION forming part of Letters Patent No. 766,957, dated August 9, 1904.

Application filed January 6, 1904. Serial No. 187,893. (No model.)

To (all 'who-117, it 'nm/y cm1/067172,:

Be it known that I, J'osnrH G. LLOYD, acitizen of the United States, and a resident of Boston, in the county of Suffolk and State of Massachusetts, have invented certain 'new and useful Improvements in Hot-Air Registers, of which` the following is a specification.

This invention relates to improvements in hot-air 'registers for the purpose of regulating the admission of hot air from furnaces; and it consists in the construction and arrangement of parts, as will hereinafter be more fully shown and described, reference being had to the accompanying drawings, wherein Figure l isa top plan View of theimproved register when open, the top plate beingI partly i broken away. Fig. 2 is a longitudinal section on the line 2 2 shown in Fig. l. similar longitudinal section showingI the register closed, and Fig. 4 is an end view of the register as seen from X in Fig. l.

Similar letters refer to similar parts wherever they occur on the different parts of the,

drawings.

The register consists of a supporting-frame, an outer or top plate, a valve-box, and a slidable valve operating in said box and of sub stantially the same contour as the box, the box forming what may be termed a valveseat 2 for the valve.

The reference character A denotes a rectangular frame of known construction and which is arranged in the lioor or wall opening, as i's common in hot-air registers. The frame A is suitably cut away to form a continuous shoulder, and against said shoulder abuts the top plate B, and by such an arrangement the outer face of the top plate B is flush with the outer face of the frame. The top plate B is provided with a series of hotair-outlet openings and an imperforate marginal flange The marginal portion t of the top plate B extends upon and is supported by the frame A. To the lower face of the marginal portion Z1' of the plate B is secured, as at Z22, a valve-box open at its top and comprising in its construction an imperforate end wall O, a slotted or perforated end wall O', a slotted or perforated bottom O2, and a pair of slotted or perforated side walls O". The valve-box extends through Fig. 3 is a` portion of said valve, as shown.

the frame A, and the width and length of the said box are such as to form between it and the said frame A a circumferential space D, closed at one end by the marginal portion b of the plate B.

Within the valve-box is located a correspondingly shaped slidable register valve composed of a pair of upwardly-eXtending imperforate ends E E', a slotted or perforated bottom E2, and a pair of upwardly-extending slotted or perforated sides E1. The said register-valve is adjustable within the box or valve-seat from the open position (shown in Figs. 1 and 2) to the closed position (shown in Fig. 3) and intermediate, as may be desired, according to the amount of hot air to be eonducted to the room that is to be heated.

In practice I adjust the position of registervalve relative to its seat by manipulating a knob or button e, secured Ato any convenient The slots or perforations in the betteln of the box or valvoseat register with the-slots or perforations in the bottom of the register-valve when the register is open, as shown in Figs. 1 and 2, and when in such open position the slots or perforations in the sides of the register-valve register with the slots or perforations in the sides of the box or valve-seat, as shown in Figs. l and 2.

By moving the register-valve to the position shown in Fig. 3 the device will be closed by the imperforate portions of the sides and bots tom of the register-valve registering with thc corresponding imperforatc portions in the side walls and bottom of the box or valve-seat, and when in such closed position the slotted or perforated end O of the valve-seat is closed by the imperforate end E of the register-Valve, thus preventing any escape of hot air at this point.

It will bev noticed that the circumferential space D intermediate the frame A and box or valve-seat is always closed by the marginal portion L of the plate B, and consequently no hot air can at any time escape directly through such space D.

When the registerwalve is wholly or partially moved to open position, `the heated air passes upward through the slots or perform IOO tions in the bottom of the valve-seat and bottom of the valve and also into the peripheral' space D and through the slots orperforations in the side walls of said valve-seat and valve, as well as through the slotted or perforated end wall C', all as indicated by arrows in Figs. l and 2.

By the construction of this my improved device the supply of hot air from the furnace can be regulated with great nicety or altogether shut off, as may be required.

It will be noticed that as the register-valve and its valve-seat are perforated in the bottom as well as in their sides the capacity for supplying hot air to the room is greatly increased as compared with devices of this kind in which the air is only conducted through bottom openings in the register device.

What I wish to secure by Letters Patent and claim isl. A hot-air register consisting of a sunken valve-seat having a closed and a perforated end. perforated sides and perforated bottom, combined with a correspondingly-shaped adjustable valve having a perforated bottom and l sides and imperforate ends, one of the' imperplate, the length and width of said frame being greater than that of the valve-box, so as to form a circumferential opening around the said box, one end of said opening being closed by the marginal portion of said plate.

3. A hot-air register comprising a perforated outer plate having a marginal portion, a valve-box secured to the lower face of said marginal portion and provided with a perforated end, an imperforate end, a perforated bottom and perforated side walls, a slide-valve in said box and having' upwardly-extending imperforate ends, perforated bottom and upwardly-extending perforated sides, and means for sliding said valve in said box.

4. A hot-air register comprising a perforated outer plate having a marginal portion, a valve-box secured to the lower face of said marginal portion and provided with a perforated end, an imperforate end, a perforated bottom and perforated side Walls, a slide-valve operating in said box and having upwardlyextending imperforate ends, perforated bottom and upwardly-extending perforated sides, means for sliding said valve in said box, and a supporting-frame for said plate, the length and width of said frame being greater than that of the box so as to form a circumferential opening around the box, one end of said opening being closed by the marginal portion of said plate.

In testimony whereof I have afixed my signature in presence of two witnesses.

JOSEPH G. LLOYD.
